BOlLER-CLEANER.

SFECIFICATION forming part of Letters Patent No. 323,310, dated July 28, 1885.

Application filed February 7, 1585.

To all whom it may Concern:

Be it known that I, FRANcrs M. FORMAN, a citizen of the United States, and a resident of Greenville, in the county of Montcalm and State of Michigan, have invented certain new and useful Improvements in Boiler-Cleaners; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a longitudinal vertical sectional view of a steam-boiler to which my improved cleaning apparatus has been applied. Fig. 2 is a front view ol' the boiler with its attachments, and Figs. 3, +L, and 5 are vertical transverse sectional views taken, respectively, on the lines x, y y, and e z in Fig. l ofthe drawings.

The same letters refer to the same parts in all the gures. l

This invention relates to steam-boilers; and it has particular reference to an improved cleaning apparatus for the same, having for its object to provide a device of this class which shall possess superior advantages in point of simplicity, durability, and general eiiiciency.

With these ends in view the invention consists in the improved construction and arrangement of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, A designates the body of a steam-boiler, and B B the heads or ends of the same. The said heads are connected in the usual manner by lines or fire-tubes.

Located in the bottom of the waterspace of the boiler, and tting neatly against the said bottom, is a curved plate or scraper, C, having a perforation, D, in vwhich is secured a forwardlyextending tube, E, extending out through a tubular bearing, G, which projects forwardly from the front end or head of the boiler, as shown in the drawings hereto annexed. The rear end of the tube E is provided with a seat, I-I, for a check-valve, I, the operating-rod .I of which extends forwardly and out through the front end of the tube E, where (No model.)

suitable mechanism may be provided for the operation of the said valve-rod.

The inside of the boiler is provided at its lower front and rear edges and at its upperY rear edge with brackets K Ii, having bearings for the guide-pulleys L L, and at the upper front corner of the boiler is a bracket, M, having bearings forashaft, N, carrying a grooved and corrugated pulley, O,v and a pinion, I?, engaging a pinion, Q, upon a longitudinal shaft, Q', that extends through the front end of the boiler, and is provided with a crank, R, by means of which it may be conveniently manipulated.

As shown in the drawings, the shaft Q with its attachments may be journaled in a plate, S, which is secured in a hand-hole, T, in the front head of the boiler by means of a clasp, U, and a nut and bolt, V W.

A chain, X, the ends of which are attached to the front and rear sides of the plate or scraper C, passes over the pulleys L L L and O, thus enabling the said plate or scraper with its attachments to be moved longitudinally in the boiler by simply turning the crank R.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood.

By turning the crank R the scraper Cwill be moved longitudinally in the bottom of the boiler, thus loosening the mud or sediment which has settled there, and enabling it to pass out through the tube E when the valve I of the latter has been opened. After the operation of cleaning the boiler has been finished the said checlrvalve is closed, and the plate or scraper C returned to its original position.

Having thus described myinvention, I claim and desire to secure by Letters Patent of the United States* l. In a boiler-cleaner, the combination,with a plate or scraper longitudinally movable from end to end of the bottom of the boiler, of an exittube extending forwardly from the said plate, and a check-valve at the rear end of the said exit-tube, substantially as and for the purpose herein set forth.

2. In a boiler-cleaner, the combination,with a plate or scraper longitudinally movable in the bottom of the boiler, and having a forwardly-extending exit-tube, of a check-valve IOO ner, an operating` crank, and a drive-ohain passing over the several guidepulleys and the drive-pulley and attached to the front and rearsides of the plate or scraper, substantially as and for the purpose herein set forth.

In testimony that I claim the foregoing as my own I havehereunto afxed my signature in presence of two witnesses.

FRANCIS M. FORMAN.
